Audio to MIDI Converter
Audio to MIDI transcribes a recording into notes. You upload a melodic performance — a hummed line, a piano take, a guitar part — and get a .mid file carrying the pitches, the timing and the velocities, which any DAW will open and let you edit, requantise or hand to a different instrument.

How it works
- 1
Upload the recording. A monophonic or lightly polyphonic melodic part transcribes far better than a full mix.
- 2
Run it. The transcription reads pitch and onset from the audio; there is nothing to configure.
- 3
Download the .mid and open it in your DAW. From there it is notes: fix a timing, change the instrument, transpose the whole thing.
What you give it
One audio file containing a melodic performance. No parameters.
What you get back
A standard MIDI file with note pitches, start and end times, and velocity. It is editable data, not audio, so what you do with it afterwards is unconstrained.
WAV, FLAC and MP3, at 44.1 or 48 kHz and 16 or 24-bit. You pick the container and the rate on the form before you run it.
Who it is for
Composers who hummed an idea into a phone and want it as notes. Producers rebuilding a part on a different instrument. Game audio teams turning a reference melody into something a synth can play adaptively at runtime.
What it costs
Priced per run with the estimate on the form. A failed transcription returns the hold in full.
Every run is a queued job. It holds its credit estimate while it works and settles to the real cost when it finishes; if it fails or you cancel it, the hold is released in full. You see the estimate before you spend anything.
Licence and ownership
Everything you generate is royalty-free for commercial use — client work, monetised video, games you sell, ads. No per-use fee and no attribution requirement. Generations are yours; uploads stay private by default, and the inputs to the isolator and splitter are deleted automatically.
Common questions
- What kind of recording transcribes well?
- A clear melodic line — one voice, one instrument, not buried in a mix. If you want a part out of a full track, split it with the stem splitter first and transcribe the stem; that is two jobs, and it is the difference between notes and noise.
- Can it transcribe drums or chords?
- It reads pitched material. Percussion has no pitch to transcribe, and dense chords transcribe less reliably than a single line. Treat the result as a starting point you edit, which is what having it as MIDI is for.
- What do I get as a file?
- A standard .mid file. Every DAW opens it, so the output is not tied to this platform — you can transcribe here and never come back, and the file still works.
